Dealing with transformer hum

I've got to agree. Mine hums if the dryer is running (I told my wife I'd beat her if she does THAT again!), microwave, etc.... I don't like to use a power conditioner with this amp. It normally sees duty as a sub amp, and the hum is never noticable there.

But, now I've got it hooked up in my main stereo system so I can track down a problem with my Audio Note amp. Mated to the Supratek Syrah with 93db AN speakers, any noise on the amp end comes through.

Admittedly, it's a pain in the A@#, but I do like the amp. So, I just have to be careful to schedule my listening time when the old lady's not home to turn shit on and annoy me! FWIW

My rig uses short paths throughout run from pole to meter base/through dual dedicated to units(less 40')second breaker after a/c,yet I heard torriodial humming late evening when the noise floor drops.
Tracked it down by throwing breakers off line one by one. Narrowed down the offending circuits,outdoor lighting transformer,toothbrush charger,cheap radio,refrig. So now I just throw those breakers off,when turning on the audio breakers.Ahhh ,the details emerge from a black hole now!

Interesting ideas. I don't know how thrilled my parents will be at me cutting off their electricity for my late night listening sessions. Hopefully they have some candles nearby or something. I kid.

Thanks for all the input. Like most Belles users, I really love my amp, save for this one annoyance that I can hopefully solve.

I have some Quiet Line (by Audio Prism) on order as my dealer recommended placing these on the same outlet as my refridge (which causes a humming/hiss in my speakers) and he also said anything ciruit that has a motor in it... so I'll have one on each outlet for my stereo and one in every circuit in my house to help keep things as quiet as possible.

I had hissing and crackling in my speakers and tracked this down to my computer equipment (that's what I do for a living so I have tons) and I researched it hear on audiogon and some people suggested putting my Ultimate Outlet in front of my computer equipment to keep it from poluting my ac lines, and sure enough I stuck it before my UPS and suddenly I had quiet, I have a little bit of tube hiss right now that I didn't have on another circuit in my house so I can't wait to put the Quiet Lines in to get to that next level.

I had this problem with Cary monoblocks once. FIND THE LIGHT DIMMER IN YOUR HOUSE! When the lights were dimmed, meaning resistance in the AC line, the transformers would buzz like crazy. That was the problem for me, anyways! Good luck!
